. This invention relates to windshield ventilatorsand more particularly to the type adapted for use on automobiles having closed bodies, such as sedans, coups, and the like. 3 The principal object of the invention is to simplify and improve devices of this character, to render them simple and eiicient in constructionand operation, and not liable to get out of order.l

Another object of the inventionis to pro` vide friction means for holding the ventilator in desired positions of adjustment.

Still another object of invention is to provide an improved tensioning devicefor the friction means.

Other objects and features of novelty will be apparent` as the following description proceeds, as taken in conjunction with the accompanying drawings, in which Fig. 1 is a partial section through the upper portion of a closed car body, showing the improved ventilator in section;

Fig. 2 is an elevation, partly in section, of u the device as it appears from the interior U of the body.v

Referring more particularly to the drawings, the ventilator is illustrated in connection with a portion Iof the body of a closed car, having a roof 10, a visor 11, a windshield 12 and a corner post 13. The windshield 12 terminates below the roof 10, leaving a rectangular opening in which the ventilator indicated generally at 15, is mounted.

Secured to the corner post above the wind- 35 shield are a pair of brackets 15, one for each.v

side of the car. Each bracket has an upstanding flange 16, which projects both inwardly and outwardly with respect to the windshield, and provided with a circular rim 17, thus forming a flat bottomed cup-like bracket to receive the ventilator. The bracket 15 comprises a fiat flange 18, drilled or otherwise provided with holes' to receive screws or other fastening means by which it may be rigidly secured to the corner postl or other frame-work of the closed car.

The ventilator comprises a semicircular I trough-like member of sheet metal or other desired material, the open ends of which are enclosed, as by means vof, abrass ferrule 19.

This ferrule is adaptedto liesnugly within the rim 17, and is provided with a central'.`

boss 20, which is rotatably mounted upon a. similar but smaller hollow boss 21 which pro-l jects inwardly from responding flan e 16. 1

Referring to ig. 1, it will be noted that when the ventilator is in the closed position,

the inner edge 22 of the ventilator abuts v against thetop of the windshield 12, whereas the lupper edge 23 of the ventilator is adjacent to the roof 10,v and as the rim 17 prevents entrance of air at the end of the trough-like member, the ventilation may bel totally cut; l.

off if desired. An operating handle 24 is' provided for `the ventilator, by means of "the center of the corwhich it may be rotated about bosses 21.

When the edge 23 is rotated inward,the edge 22 will bermoved outward away from-the Windshield 12, and further rotation will increase the size of the ventilation opening. The cylindrical contour of the-inner surface ofthe ventilator will tend to deiiect `the ncomingair, and to. distribute it throughout 1 Y thebody of the automobile.

` To'retain the ventilator in desired position-s as theboss 20.0fthe ferrule 19 which forms v a seat for the inner end thereof. The outer end of the spring 28 is contained by va cap 29 having a rectangular opening to permit it to pass over the squared portion 26. A thumb screw 30 isprovided `with a threaded internal bore adapted to encase the threaded end 27 and project thereoverto engage the cap 29. By means of the thumb screw 30, the pressure exerted by the spring 28 may be adjusted as desired, thus regulating the pres* sure between. the ferrule 19 and the flange 16.

A member having a friction surface is interposed between these two elements, and inv thepresentembodiment of the invention I have shownbrass washers 4for this purposev as shown at 31, but obviously other materials Would serve for this purpose.

It should be readily apparent that by adjustment of the thumb screw the friction between the ventilator and the bracket may be readily adjusted so that the ventilator may be easily7 moved to any desired` position, and that the ventilator will stay in this Vadjusted position until again adjusted.

While one embodiment of the inventionl has been shawn and described in great detail for the purposes of adequate disclosure, the invention is not limited to the specifi'cdetails disclosed, but includes such modifications and embodiments of the broa'didea as come within the scope of the appended claims.-

Having thus described my invention, what I claim as new anddesire to secure by Letters Patent of United States is l. A; windshield ventilator for a closed car body having a windshield anda visor, and adapted to be inountedin anv elongatedhorizontal opening aboif'e the windshield in baclf; of the visor, the improvement which comprises a closure member pivoted to swing about the longitudinal axis ot' said'opening', bracket members at each end ot'said opening for guiding said closure member, means interposed Vbetween saidclosure member and one of said bracket members for holding them in' relatively adjusted positions' and means coaxial with'the pivot points ofV said closure member for tensioning said holding means. Y

2. In combination with a vclosed car body havinga ventilator, a bracket-mounted on said body havingan upstanding flange with an annular rim, a closure men'ibe'i` pivoted centrally of said flange and having anarcuate end guided by said rim, frictionfmeans interposed between said flange and arcuate en'd. A y

3. In combinationwitli a closed carbody having. a ventilator, a bracket mounted on saidI body having an upstandii'igflange with' an annular rim, a closure member pivotedl centrally of said lange and having an arcuate end guided by 'said'rinn friction means interposed between said flange and arcuate end and means for tensioning's'aid frictionl means.

4. In a closedrca'r ventilator, aibracketha;L ing an up'standing flange withi anannular rim? and a central` boss, ay closure member having an arcuate end with aboss pivotedon the first mentioned boss, and means passing-` through both said bossesA for holding said closure member invarious'adjusted positions.'

5. In aclosed car ventilator, a bracket hav=` .f ing an unstanding flange with an annular rim and a central boss,- a closure member 'having an arcuate-end with a-boss'pivotedon-fthe first mentioned boss, and=V meanse .passing through both `said, bossesffor ,holdingsaid .closure `-nie1i1ber in various adjusted-positions,

said means comprising a bolt, a cap carried by said bolt, a thumb screw retaining said cap, and a. spring interposed between said cap and said arcuate end for urging it against said flange.

6. In a closed car ventilator,` a support member securedto a portion of said. body, a closure member, means for pivtally mounting's'aid closure member on said support, and

lmean-sin addition to the aforementioned meansY carriedby said `supportand passing through said closure member solely for retainingsaid'4 support and closure member in relatively adjusted position.

7: In combination; a pair of spaced members, a ,windshield glass engaging said lspaced members at itselids, glass terminating at its upper edge below the upper ends of said spaced members to leave -an elongated ventila' opening, bracket positioned in each end of said opening,each' bracketcomprisin'g aflangefor securing it to on'e'of saidV spaced members and a culpllike vportion consisting ot' an' end wall positioned to project forward-V lyaiidrearwardly of the i'alanef of the' windsl'iield' and a rim around the edge of said end wall, anda' ventilator pivotally supportedon said brackets ivitliits ends received insaid cub-like portions. y l y In testimony wl'iereof I alliX my signature;
